fort of a compound having cement mixed therewith, which when set hardwill give a substance simulating in appearance and texture marbles ofvarious types.

Another object of the invention is the provision, in .a manner ashereinafter set forth, of a compound adapted to become hardened and whenso formed to imitate marble of various type, and further having a ualitywhich is well adapted to take a hig polish the same as real marble.

A further and final object of the invention is the provision, in amanner as hereinafter set forth, of an artificial marble which in allrespects is indistinguishable from the natural product, the ingredientsof which artificial product are inexpensive, and therefore may becombined to produce at small cost, an article fully equal in everrespect to the most expensive and beautifu type of marble.

The invention comprises the mixing together of silver sand, marble dust,beeswax, tur entine and cement, together with any desira le colorinmatter, either single colors or of mixed co ors. The particular types ofY I cements used are those known as A tlgs ghite and Portlagd whitecements; taking prefer-' ably equal partso each. These ingredients arethoroughly mixed together and the .proper amount of water added to makean easily handled pourable mix. The mixture is then turned into moldsand allowed to solidify. After becoming thoroughly hardened, thesolidified mixture is then worked upon with the polishing mixtures ortools and a very high polish may be imparted to the article.

Through extensive experimentations to d termine the various portions ofingredients necessary to produce a perfectly blended mixture, apphcanthas found that the best results has been obtained when combining theingredients in approximately the follow- Application filed April 10,1925.

s a ove stated t se mgre len s are thoroughly mixed and sufiicient wateradded thereto to make a pourable mixture.

In mixing the coloring matter directly with the other ingredients, thesame can be put in after the other ingredients have been thoroughlymixed, and thereafter the mix so stirred so that the coloring materialswill streak therethrough and when the mixture has set the colors will beextended throughout the set body and same can be cut in any desiredmanner without fear of getting below the coloring matter therein, aswould be the case in cutting other colored artificial marble where thecoloring matter is only veneered on to the surface or does not permeatethe entire mass of material.

In order to further strengthen the product resulting from the formationof a mass after the formula given, applicant passes through the bodysuitable strengtheningwires so that upon the setting of the mass thewires become firmly imbedded therein and add rigidity to the body.

Articles made in connection with the for- 'mula above set forth havebeen found to be strong and durable and to take a high polish, to giveto the same the appearance of a natural high grade marble.

Having thus described my invention what I claim is:
